Magnetic Float Type Level Gauge



The magnetic float type level indicator had been developed by our excellent engineering technology based on our rich experience. This type indicator is of good performance and maintenance free due to tempered glass so that this can be widely for other chemical well as liquid(HFO, DO, CO2, LPG, fresh water) without limitation of marine and industrial fields.

Operating Principle

The rotor indicator(liquid:red, vapour:green) are easy to read from a distance. The indicator is separate from the measured medium, so you can use a suitable indicator where the sight glass is not subject to consideration. Rotor indicator is mounted to the front chamber. As the liquid level changes up for down, each magnetic rotor turns and shows white or red by magnetic force of magnet builting float. Once it has been turned it remains as it is showing one of the colors until the reverse magnetic force of the magnet float is effected.
